Intracerebral hemorrhage (ICH) is a common nervous system disease, its mortality and disability are very high. However, the mechanisms of brain injury after ICH have not yet been fully explained. "[he latest studies have suggested that iron overloading plays an important role in the brain injury after ICH. This article reviews the advances in research on the distribution and function of iron in the brain, the mechanisms of brain injury caused by iron overloading after ICH as well as the use of iron chelator.

Aneurysmal subarachnoid hemorrhage accounted for 70% of subarachnoid hemorrhage. The high fatality and disability rate affected patients′ quality of life. Aneurysmal subarachnoid hemorrhage should be considered as a chronic cerebrovascular disease, and it is very important to take early intervention and strengthen the secondary prevention to the patients with risk factors for disease. This paper reviewed the research status on quality of life of patients with aneurysmal subarachnoid hemorrhage and its influencing factors, in order to provide a reference for neurological physicians.

Objective To provide the basis for the differentiation with similar species of intestinal flukes through observing the figure of Haplorchis pumilio. Methods Adults of H. pumilio were collected from the intestine of the cat which was infected with the encysted cercariae of H.pumilio for 45 days. The worms were observed after staining. Eggs and metacercariae of H.pumilio were collected and examined for their shape, size and morphological characteristics. Pseudorasbora parva, the fish host, was examined for the parasitized sites of metacercariae. Results The principal characteristics of the adults is the acetabulum degradation. There are only the genital sucker with 44-48 hamuli. The average measurement of eggs is 31.2?16.7 ?m with a smooth shell. Its aceromion is not evident. The average diameter of metacercariae is 168.5 ?m. There are squamous spines on metacercaria. The metacercariae only parasitize in the muscle between the basis of the fin and the fish body. The average measurement of metacercaria cyst is 445?95?m, with squamous spines on the body surface. Hamuli are found on the genital sucker of metacercaria cyst. Conclusion The morphological figures and parasitic sites of metacercaria, the genital sucker of the adult, and the number and form of the hamulus on the genital sucker provide basis for distinguishing H. pumilio from other intestinal flukes.

Background In recent years,some researches had been conducted on the pathologic changes of the secondary injury of perihematoma in animal experiments,but only a few studies had been done on the dynamic pathologic and ultrastructural changes of the perihematoma in ICH patients. The unique contribution of our study is to investigate the dynamic pathologic and ultrastructural changes of the perihematoma in ICH patients and provide significant insights into how the pathophysiology and ultrastructures changed after ICH.Methods The written informed consents were obtained from the ICH patients or their relatives. 30 patients (the supertentorial hemotoma volume＞30 mi and the cerebellar hemotoma volume ＞10 mi) were divided into 8 groups according to the time passed after ICH:＜6 h (6 patients), 6 ～ 12 h (7 patients), 12 ～24 h (5 patients), 24～48 h (3 patients), 48 ～72 h (3 patients), 3 ～4 days group (3 patients), 5 days group (2 patients) and 8 days group ( 1 patient) and subjected to craniotomy for hemotoma evacuation. During the operation for the hemotoma's evacuation, a small amount of tissues that must be removed, which located at 1 cm near the hematoma, were taken as experimental groups; And the same tissues of 7 patients (＜12 h), which were far from the hemotoma on the operational way, were taken as control group. The pathologic and ultrastructral changes were observed.Results The tissues of the control group were almost normal while the damages of the tissues from the experimental groups were slight in ＜6 h groups, more severe after 6h and got to the maximum between 24 ～48 h , recovered gradually after 72 h, became similar to the 6 ～ 12 h group on 5 th day, got better on 8 th day and resembled the 6 h group.Conclusions The injury of the perihematoma occurred in early stage, reached the peak level between 24 and 48 hours after ICH; which was consistent to the clinical nervous functional deficits in the ICH patients.
